List of hyperfine structure of the elements?

Click For Summary
SUMMARY

The discussion focuses on the hyperfine structure frequencies of various elements, specifically highlighting caesium-133 at 9,192,631,770 Hz and hydrogen at 1,420,405,751.7667 Hz. Participants express interest in locating comprehensive lists of hyperfine structure frequencies for other elements and isotopes, noting a 2016 paper detailing newly discovered lines of lanthanum that contains several hundred entries. The conversation raises questions about identifying patterns in these frequencies and the challenges of accessing relevant research, particularly non-English publications.

PREREQUISITES
  • Understanding of hyperfine structure in atomic physics
  • Familiarity with frequency measurements in spectroscopy
  • Knowledge of isotopes and their properties
  • Ability to conduct academic research and access scientific papers
NEXT STEPS
  • Research "hyperfine structure of elements" for comprehensive lists and studies
  • Explore the paper titled "Newly Discovered Lines of Lanthanum Between 5600 Å and 6100 Å" for insights
  • Investigate methods for predicting frequencies of isotopes based on existing data
  • Learn about spectroscopy techniques used to measure hyperfine structures
USEFUL FOR

Researchers in atomic physics, spectroscopists, and anyone interested in the detailed study of atomic structures and their frequencies.

If caesium 133 frequency for its hyperfine structure is 9 192 631 770, and hydrogen is 1 420 405 751.7667 what are the frequencies for the other elements and their isotopes? Is there a list on line some were because this would be a long list. Any help on where to look on line would be appreciated. Thanks.

I have found a paper with a list of "Newly Discovered Lines of Lanthanum Between ##5600 \,Å ## and ##6100\,Å ##" published in 2016. Their list alone contains several hundred entries. This raises the question: Why?

I want to see if there is any patterns in the frequencies. Maybe you could predict the frequency of an isotope or maybe other information. I know other people must of looked at this but I am still curious. How can I find this paper? Thanks.
 
The paper wasn't in English. I don't think there is a chance to identify patterns, at least not manually, but I don't know. I just found it (quickly) as I searched for "hyperfine structure + list" and was surprised to find so many for just one element and even labelled "new".
 
The patterns for hyperfine structure as as "patterned" as those for any other energy level.
